Re: B&C Sub designs A double 18 can be one large enclosure or two separate enclosures. As long as the net volume per driver is the same. A 16 cf enclosure with two 18's will be the same as an 8 cf cabinet with one driver. This assumes Fb and port area per driver are the same. One reason to have the double 18 box divided into two chambers is that if you blow one driver then the single driver is effectively in a huge cabinet and exposed to the blown driver's cone flopping around as well which makes it likely the second driver will be damaged as well. I'm sure there are other reasons but that is my understanding.Loren
